Supported Preview Types

MakerVault renders as many file types as possible natively in the preview, without needing to open external applications.

Native rendering

These file types render directly in the preview:

Type	How it renders
SVG	Full vector rendering via native <img> element
PNG, JPG, WebP, BMP, GIF	Native image rendering
TIFF	Converted to PNG via macOS sips
PDF	First page rendered via macOS sips conversion
AI, EPS	Rendered via macOS sips PNG conversion
TTF, OTF, WOFF, WOFF2	Font sample showing uppercase, lowercase, numbers, pangram at multiple sizes
G-code, NC, TAP	Plain text preview of the first 200 lines

LightBurn files

LightBurn files (.lbrn and .lbrn2) get special treatment:

• If the file contains an embedded thumbnail, MakerVault extracts and displays it
• The metadata panel shows cut settings (layer name, type, speed, power)
• Text elements and notes from the file are displayed
• Falls back to a placeholder if no thumbnail is embedded

Placeholder preview

File types without native preview support (DXF, CDR, STL, 3MF, OBJ, xTool, RDWorks, VCarve Pro) show a placeholder icon with the file type label. You can still see all metadata and use the “Open in [App]” button to view the file in its native application.

Expanded file row

In addition to the Spacebar overlay, you can expand a file row inline to see a 3-column layout:

1. Preview — Thumbnail or rendered preview
2. Info + Notes — File details and editable notes
3. Metadata — Embedded metadata (LightBurn cut settings, etc.)
